If your solar system is positioned & pitched correctly you could pay off your system in 3 – 5 years. Typically a 5kw system saves you $2000 per year, 10kws $4000 per year. So over a 20 year lifecycle of a 10kw system with quality panels is $80,000. Less installation costs. Your still looking at close to $70,000. So yes it’s very worth making the switch to solar today.
